Koffie Yinkah — “I believe the Hesselbein Global Academy annual fellowship programme was vital for me as a potential public servant of South Africa to serve the people of this country in government one day.” – Kofi Yinkah

University of the Free State (UFS) third-year BAdmin student, Kofi Annan Yinkah, formed part of the Hesselbein Global Academy annual fellowship programme, hosted by the University of Pittsburgh in the United States of America (USA). Originally from the East Rand in Johannesburg, Kofi represented the UFS as one of the top-50 students who were selected out of 450 global applicants.

The Hesselbein Global Academy annual fellowship programme aims to connect young leaders from all over the world with well-equipped professionals who are leaders in the fields of business, government, and education. This programme was established for the purpose of cultivating and producing cadres who will become experienced ethical leaders, armed and qualified enough to address and solicit solutions for critical issues experienced by diverse societies throughout the world.

“The fellowship covered topics that have helped to broaden my critical thought processes and concerns about societal issues in our country and all over the world. It has also emphasised the importance of implementing change through effective governing-policy development and establishment,” Kofi says.

He describes his experience at the fellowship as “out of the ordinary,” and believes that it has had a progressive influence on his life. He explains how it has unlocked his mind through enlightened engagement with student leaders from various countries in the world, including Nigeria, England, Canada, Chile, Trinidad and Tobago, Vietnam, China, United States of America, and Ireland.

One of the most important tools he believes his experience has equipped him with, is understanding the significance of employing a solution-driven approach to various situations. He is confident that this will give him the necessary skills and knowledge to work effectively in teams.

Kofi explains that he found out about the fellowship programme via social media. He encourages UFS students to use online platforms to source information about opportunities that can offer them meaningful experiences for learning and growing.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.

The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
